Filed: 1985-02-19
Abstract: PURPOSE:To secure good printing quality by preventing dust or air bubbles from flowing into an ink flow channel, by providing a filter having a linear open diameter between the ink supply channel and ink tank of a head. CONSTITUTION:A filter consists of a mesh part 2 formed by electroforming and having shaped opening parts provided with parallel side intervals of about 10mum or less, a fixing part 3 provided with opening parts each having larger diameter and locating holes 4a, 4b and the mesh part 2 is constituted of filter apertures 5 each having an oval shape wherein the interval d1 of each parallel side is 10mum or less and the length d2 thereof in the longitudinal direction is 100mum or less. As mentioned above, if the parallel side interval d1 of each filter aperture 5 of the mesh part 2 is 10mum or less, air bubbles with a diameter of 10mum or less passing through the filter aperture 5 are dissolved prior to reaching a pressure chamber. In order to generate no clogging due to dust, it is desirable to set the parallel side interval of the filter aperture to a diameter range from 4-10mum.

Title: Production of 2,3-diaminoacrylonitrile derivative
Inventor: TAKEBAYASHI MICHINORI
IPC: C07C323/63
Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To obtain a 2,3-diaminoacrylonitrile derivative useful as an intermediate for medicines, agricultural chemicals, etc., in a high yield in a short time by a complicated operation-saved process comprising reacting hydrogen cyanide with a sulfide compound under specific reaction conditions. SOLUTION: This method for producing a 2,3-diaminoacrylonitrile derivative comprises reacting hydrogen cyanide with a compound (sulfide compound) of the formula: RSSR or RSH (R is an aryl, an alkyl, an aralkyl, an alkenyl) in the presence of a base (e.g. triethylamine) in a slightly water-soluble solvent (e.g. xylene) at 0-50 deg.C, and subsequently adding water to the reaction solution at 0-25 deg.C to deposit the crystals of the 2,3-diaminoacrylonitrile derivative of the formula. The hydrogen cyanide and the base are added in amounts of 3-6 moles and 1-3 moles, respectively, based on the sulfide compound. The water is used in an amount of 0.5-2 times that of the solvent in dependence on the kind of the solvent. The method can save complicated operations such as the removal of the base and the addition and reaction of p-toluenesulfonic acid. Thereby, the loss of the product due to decomposition reactions, etc., in the complicated operations can be reduced.

Title: Carved bar code reading method
Inventor: WASA YASUHIRO
IPC: G06K7/10
Filed: 1989-02-10
Abstract: PURPOSE:To correctly execute reproducing even when plural carving grooves are carved with high density or when a detection distance is enlarged by knowing the width of the groove from a peak output. CONSTITUTION:A magnetic field is impressed to a metallic plate 1 and the gradient, which is generated by the impression, of the magnetic field in a direction horizontal to the metallic plate 1 or of the magnetic field in a direction vertical to the metallic plate 1 is measured by magnetic sensors 4 and 5. Then, a carving groove 2 is regraded to be in the center of a position in which a measured value obtains a pair of positive and negative peaks. When difference between the measured values of the positive and negative peaks is larger than a value set in advance, the groove corresponding to the wide groove width is reproduced and when the difference is smaller than a value set in advance, the groove corresponding to the narrow groove width is reproduced and read. Thus, even when a bar code carved with the high density is detected or when the detection distance is made distant, the carved bar code can be easily read with high accuracy.

Abstract: PURPOSE:To reduce the amount of warpage of an entire wafer by forming in advance grooves on predetermined regions of a first semiconductor substrate when forming a second semiconductor by a molecular beam epitaxy method or an organic metal vapor growing method on the substrate. CONSTITUTION:A semiconductor substrate 1 is an Si wafer, grooves 3 are formed by etching at scribing grids between element forming regions in depths of the same degree as the thickness of a GaAs film to be grown or larger. A GaAs layer is grown, for example, by a molecular beam epitaxy method on the substrate. The growing method includes the steps of heating an Si substrate in high vacuum, cleaning the surface of the substrate, then depositing Ga in As atmosphere, and first growing an amorphous GaAs layer. Then, the substrate temperature is raised to crystallize the amorphous GaAs layer, and a GaAs single crystal is grown at a predetermined temperature on the layer. The grooves are thus formed to reduce the warpage of the wafer.
